Preparations are underway for California's largest gun show, just days after the shooting massacre in Las Vegas that claimed 58 lives.

The Crossroads of the West Gun Show opens Saturday, Oct. 7 at the O.C. Fair and Event Center in Costa Mesa. Roughly 10,000 people are expected to attend the two-day event.

But some Costa Mesa residents are questioning the timing of the gun show.

"Doesn't seem very appropriate," said Kim Dexter, "If nothing else, just to be mindful of what happened, you think you might want to delay that."

The owner of The Crossroads of the West Gun Show, Bob Templeton, said he considered postponing the event. "The random acts of a madman have impacted the lives of literally thousands of people," Templeton said.
